Algodoo

No, it`s not fast, it`s extremely slow. Don`t expect much. Hit A first and hold until you reach the finish. When you reach the hill hit S and hold. You should hit the finish at 50 meters/second, or if you`re less lucky, the tank explodes.

It can`t go much faster because of the bloody unlimited stretchable hinges. If the stretchability of the hinges could be limited this design could probably easily do 200, but it can`t.
